Re: Ruby on Rails will ship with OS X 10.5 (Leopard) - HOLY CRAP!

from what DHH said, they're implementing it as a gem and not some apple-only install system, which is great because updating will be nice and simple, and gem is a great standard. (too many times when companies do these type of things they screw it up by trying to dominate it, or by putting their 'shine' on it)
